Dune! Move Over!

Sand dunes are inanimate objects, so they don't think or feel.
However, CNN reports new research reveals sand dunes can communicate with their neighbors and let them know they need space.
Cambridge University scientists made the discovery after putting two identical piles of sand in a tank that generated enough water flow to move the particles.
Sand dunes are known to move around, or migrate, in rivers, oceans and deserts and smaller dunes generally move faster than larger ones.
